摘要：
The present invention relates to a dental composition comprising a polymerization initiator system comprising an aromatic tertiary phosphine compound, as well as to a use of said aromatic tertiary phospine compound for the preparation of a photocurable dental composition. In particular, the present invention relates to a dental composition comprising (a) one or more compounds having at least one polymerizable double bond； (b) a polymerization initiator system comprising (b1) a sensitizer； and (b2) an aromatic tertiary phosphine compound of the following formula (I): Z-R (I) wherein Z is a group of the following formula (II) R(Ar)P-(II) wherein R1 represents a substituted or unsubstituted hydrocarbyl group； Ar represents a substituted or unsubstituted aryl or heteroaryl group； R is an aryl group, which may be substituted by one or more groups selected from a hydroxyl group, an amino group, a –NR2R3 group (wherein R2 and R3, which may be the same or different, are selected from C1-6 alkyl groups), a carboxyl group, and a group having a polymerizable double bond； wherein the group R and Ar may be substituted by one or more groups selected from a hydroxyl group, an oxo group, a –NR2R3 group (wherein R2 and R3, which may be the same or different, are selected from a hydrogen atom and C1-6 alkyl groups), a carboxyl group, and a group having a polymerizable double bond, and L may be substituted by one or more groups selected from a hydroxyl group,an oxo group, a –NR2R3 group (wherein R2 and R3, which may be the same or different, are selected from a hydrogen atom and C1-6 alkyl groups), a carboxyl group, and a group having a polymerizable double bond.La présente invention concerne une composition dentaire comprenant un système d'initiateur de polymérisation comprenant un composé de phosphine tertiaire aromatique, ainsi qu'une utilisation dudit composé de phosphine tertiaire aromatique pour la préparation d'une composition dentaire photodurcissable.
